Explanation:

Incorrect. Algae is not typically considered a particulate pollutant in air. Particulate pollutants usually refer to tiny solid or liquid particles in the air, such as dust, smoke, and soot, which can have harmful effects on human health and the environment. Algae primarily exist in aquatic environments and are not a common component of air pollution.

Correct. Scrubbers are indeed used to clean air from both dusts and gases. They work by passing polluted air through a wet or dry packing material, where the pollutants are removed either through absorption or chemical reactions. Scrubbers are effective in controlling gaseous emissions, particularly acid gases, and particulate matter.

Therefore, only one of the statements is correct.
